Human Genome Project
What is it?
The Human Genome Project is a 13 year effort that
was started in 1990.
Two of the HGP goals were:
all the approximately 30,000 genes in human
the sequences of the 3 billion chemical
base pairs that make up human DNA
What do the goals mean?
Scientists started making a map of all of
the DNA in humans.
So what does this
mean for you?
We now know where all of the genes in a
human are located.
We can determine traits and diseases
before they happen. Ex. Heart Disease
It makes transgenics possible for humans.
So What is Transgenics?
Also known as genetic engineering.
Transgenics is the moving of a gene from
one species to another.
Example: Alba “the glow bunny”
Alba has a
gene that was
taken from a
French genetic researchers created Alba for artist Eduardo Kac. Thanks to genes
borrowed from a jellyfish, the albino rabbit glows green when placed under special
lighting. In regular light, Alba appears like any other furry white rabbit. But place her
under a black light, and her eyes, whiskers and fur glow a otherworldly green.
They tried this technology with
They took the same gene from a jellyfish
and put it into a pig.
The pigs hooves
and nose glow
We have tried transgenics
with other critters.
Scientists have introduced a gene from a
fish into a tomato. The gene was for the
ability to survive cold weather. Now the
tomato can survive cold weather!
